(Ages 9 and up) Join Tom Terrific as he shows you how to attract butterflies in your yard. Tom will talk about site selection and preparation, host and nectar plants, pesticides, native plants, and much more. Tom uses pictures, video, and hands on exhibits to teach you everything you need to know to create a butterfly paradise. After the program you are invited to tour Tom’s butterfly gardens in Crestwood to see more than 200 butterfly plant species he grows. (Reservations begin April 22 by calling 314-301-1500.)
